I held for 15 mins and stated wait time 6 mins or so. On the recorded message.I bought 3 delta 2 piece round toilets in 2018. Registered them. Two already the cylinders running and water bill went from $32 to $149. Have to pay that bill. Plumber cost $60-a good price. My husband readjusted the other one running- so far ok. The other nothing wrong yet. The plumber cannot get the flappers for the 3. Please send me three flappers and 2 replacement cylinders as sure they will go out on a weekend or a major holiday as sure I will need a plumber. Otherwise, pleased. If it costs me for these parts but understand they r suppose to lasts then so be it I will pay. Regardless I need these parts. User's recommendation: message. Guess, continue to buy delta toilets.
